13 SYSTEM OPERATION WITH PRESSURE SWITCHES

Hold down the key SB1 for three seconds
electropumps start, controlled directly by the pressure switches.
ATTENTION! The AUTO and STOP buttons of each electropump are NOT active.
To exclude the individual electropumps isolate:
- FU2 for M1,
- FU3 for M2,
- FU4 for M3,
- Turn the isolating switch on the panel QS1 to "0".

Error Conditions

Check the electrical connections and the efficiency of transducers.
NB: in a sistem with a single transducer in the case of failure AL T1 the unit
automatically searches for the second transducer, if it is connected, it still
works in regolation otherwise the system pass to the switches control.

Unlock the pump manually.

Check the fuses of the motors.

Switch off power to the panel.

After waiting 5 minutes,re-supplay.

If the error persists, replace the inverter.

Shut down the plant.

Check if the parameter 124 if is properly set

Check the presence of water in the plant.

Enable the electric pumps at the march.
